RESILIENT SUPPORT FR MACHINERY.

Application filed lea-rch 2, l.

To @ZZ whom t may concern.'

Be it known that l, KARL @siren Leon, a subject oi the King ot Sweden, residing at Stockholm, in the county of Stockholm and Kingdom of `cflweden, have invented new and useful l for Machinery. ot' which the following is a specilication.

rllne object of this invention is to provide a resilient member suited to take up a load elastic-ally, where it is wanted to provide iior rather slight yielding movement also for a ieavy load and where the space in which trie yieldino' member has to be built in is comparatively limited. rhis invention is especially adapted to be utilized in connection with washersto support the loads in radial antitriction bearings.

this invention the yieldin member comprises plurality of coaxia cylinthical,yielding, metallic elements surrounding` each otl er, and inserted between each adjacent pairs ot said elements supporting members, which are disposed on obliquely displace-d spots in such a way, that when a load acts upon the member in a radial direction the load will be transmitted on to the stationary support not along a straight line but along bent lines going alternately through the yielding element and through the intermediate supporting members between each pair of the yielding elements. rilhe number of yielding elements in the resilient member Varies in accordance with the ability of springing effect as wanted. The intermediate supporting members are displaced alternately between the yielding elements suoli as tor an example concerninv one disk or element the points of support are disposed at or near the edge of said element, while concerning the succeeding element the points of support are disposed at or near the center or generally so that the points of support of two adjacent yielding elements can not be gone through by a straight line parallel to the direction ot' the yielding movement or" the member. The parts transmitting the support from one element to another either can be made in one piece with the elements proper or from separate parts placed between the elements.

grammatically are shown in the accompanying` drawings, in which- Figures l to 5 are axial sections of various embodiments of resilient members suitable to support the inner race ,ring or" radial bearings. Figs. G and are cross sections oi: resilient schilders, formed by means of torcor by pressing' and Figs. 8-10 side elevations oi various forms of cylindrical yielding members.

Referring' to iig. l, l indicates a shaft surrounded by a plurality ot cylindrical yielding rings 2 arranged concentric to the shatt and are tapered at the edges. The rings bear against cach other alternately by means oi intermediate rings 3 itted within tapered edges of the rings 2 and alter- 'lv bv means ot intermediate rings d 3 and are lrept in proper position relativel-,r

other and the shalt by means of the pins 5 or the like. 6 denotes an outer g, l the balls and 8 an inner race ror a radial ball bearing, which bears against the outermost yielding ring niembcil by means ot ribs 9 projecting radially around the race ring S ina manner correspondent to that oi the intermediate rings or ribs 3. The outer race rings are encircled by a pluinmer block l0. TWith this tapered shape of the intermediate rings 3 the yielding movement will take place at the middle ot' the rings 2 as well as at their edges, where the rings 3 are liable to move a little out and and in in an axial direction.

The embodiment shown in Fig. 2 dill'ers from the just described device as far as the intermediate rings are substituted by ribs 3a, la respectively forming parts of the rings 2 proper.

F ig. 3 shows a resilient member similar to the embodiment shown in Fig. l with the only dierence that the yielding rings 2 are not tapered at their eaves. Intermediate rings l are located centrally between the adjacent rings 2.

ln the resilient member shown in Fig. 4 each ring 2 is supported only at one place by means of an intermediate ring 3 alternately fitted at the one edge or the other of the succeeding rings 2. With this device a cnsiderable yielding ei'ect can be employed even for rather small loads.

The embodiment according to Fig. 5 consists in a cylindrical ring lln around the shaft l and provided With a plurality of ribs 3a. A cylindrical ring 2 bears against the ribs 3f and is surrounded by a cylindrical ring 1lb bearing againstV the ring 2 by means of similay ribs 3'). rlhe'ribs 3 and 3b are displaced in relation to each other so that the ribs 8b in ring llb'malre contact with the ring 2 at lines, which intersect the spaces between the ribs 8a in ring lla.

Figs. 6 and 7 shows how the cylindrical rings 2 are given such a section that the intermediate parts l2 and 13 are lirmly Withheld in proper position. Thus the rings .2 are provided alternately in the center with cup shaped grooves l/l suiting intermediate center parts l2 and-alternately at the edges withV recessed portions l5 suiting nermediate parts 13 around the edges. Either all the disks are pressed at the edges as shown in Fig. 6 or only every other as is shown in F ig. 7 These recessed types of cylindrical rings 2 canV be manufactured by pressing or Y forcing from smooth cylinders. y

The resilient cylindrical rings 2 can be completed in many different ways. ri`hus they can be axially cut up trom the ends or at their middle portion, as is shown in Figs. S and 9 respectively or by axial slots, parted in porticns in any convenient manner manufactured in standard sizes and the resilient member in every case made up of such plurality of rings that suit the load and the resilient ability' required.

Having now particularly described and ascertained the Anature or" my said invention and in What manner the same -is to be performed, I declare, that What I claim is l. A resilient member for radial antitriction bearings comprising a plurality of coaxial, cylindrical, yielding, metallic members surrounding each other, supporting members between each adjacent pairs ot said yielding members, said supporting members disposed on obliquely displaced spots as and tor the purpose set forth,

2. L resilient member for radial antitriction bearings comprising a plurality of coaxial, cylindrical, yielding, metallic mem'- Vbers surrounding each other, supporting members between each adyacent pairs ofV said yielding members, said supporting memdisposed on obliquely displaced spots, the yielding members provided with recessed portions adapted to withhold said supporting members in proper positions.

3. A resilient member for radial antifriction bearings comprising a plurality ot coaxial, cylindrical, yielding, metallic niembers surrounding each other, supporting members between each adjacent pairs of said yielding members, said supporting members displaced en obliquely displaced spots, the lyielding members provided with recessed portions adapted to withhold said supportsignature.
